ZigBee is widely used in wireless network in
Internet of Things (IoT) applications to remotely sensing and
automation due to its unique characteristics compared to other
wireless networks. According to ZigBee classification of IEEE
802.15.4 standard, the network consists of four layers. The
ZigBee topology is represented in second layer. Furthermore, the
ZigBee topology consists of three topologies, star, tree and mesh.
Also there are many transmission bands allowed in physical
layer, such as 2.4 GHz, 915 MHz, 868 MHz. The aim of this paper
is to evaluate the effect of ZigBee topologies on End to End delay
and throughput for different transmission bands. Riverbed
Modeler is used to simulate multiple ZigBee proposed scenarios
and collect the results. The results of the study recommend which
topology should be used at each transmission band to provide
lowest End to End delay or obtain maximum throughput, which
is case sensitive in some IoT applications that required for
example minimum delay time or sending high amount of data.
